This is not the rpg, just a challenge for designers who want their cards to be a little more popular.
Each card you present, under the given conditions, I will favorite it, that's all to it.
Really good cards will be used in the rpg, however.
Variant 1: Imerian Dawn
Make me plants and animals using mountain, forest, and swamp.
You can also make instants and sorceries to accompany such.
Variant 2: Alamari Tribes
Focus on headhunters, occultian forces, and warbeasts using swamp, island, and forest.
The Alamari tribes are besieged by Sangheim demons and Merfolk... but the problem belies in reaching those forces.
